MACHINE FOR OPERATING UPON INSQLES.

Application filed March 20, 1914. Serial No. 825,971.

To all whom it may concern:

Be it known that we, JOHN W. Coscnove and Emvano ERICKSON, citizens of the United States, residing at Medford, Middlesex county, and Beverly, Essex county, and State of Massachusetts, have invented certain new and useful Improvements in Machines for Operating upon Insoles; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The present invention relates to machines for operating upon insoles, and more particularly to that class of machines which form transverse cuts or incisions extending part. way through the insole at the margin thereof where the stitch-receiving groove terminates, and which also apply guiding and identification marks to one or both surfaces of the insole.

The object of the present invention is to improve machines of the above class, and more particularly machines of the general type disclosed in the patent to Miller Cook, J12, No. 957,598, dated May 10th, 1910, and in his application Serial No. 376,280, filed May 29th, 1907, by rendering the same more convenient, certain, and efiicient in operation,'especially upon soles of varying thickness and of varying densities. and further by providing for variations in the relative longitudinal positions of the cuts and guiding marks.

With these objects in View, the present invention consists in the devices and combinations of devices hereinafter described and more particularly defined in the claims.-

ln the accompanying drawings which illustrate What is now considered to be the preferred embodiment of the present invention, Figure 1 isa front elevation of the machine; Fig. is a side elevation partially in section; Fig. 3 is a plan view; Fig. 4; is a plan view with the pivot-ed head removed; Fig. 5 is a detail in vertical section taken on the li 5%} of Fig. 3, looking toward the left;- Fig, 6 is a horizontal section on'linc 6 t Figs. 1 and 2, of the front ends of the arms, and part car-r detail in vent al sc ion on the line of Fig, 4;, looking" toward the left; and

scoring the flesh side of the insole arranged to score the insole abreast of and in front of, respectively, the transverse cuts in the channel lips.

The machine illustrated in the drawings is of the same general type as those disclosed in the Cook patent and application abovereferred to, and comprises abase or frame which is provided at the front withwork supporting and guiding devices, and

at the rear with power-actuating niechanism, an oscillating head or lever pivoted midway its ends being actuated from the driving mechanism and carrying at its front end work-engaging tools or instrumentalities which cooperate with other worloengaging tools or instrumentalities carried by the base of the machine.

The base or frame 1 of the machine, hav-' this construction being substantially as shown in the Cork application. In order to avoid accidental movement of the handle and dial and displacement of the gage. the handle and'dial are splined upon the shaft 6 and the rear face of the dial is provided with a series of notches 9 to receive a tooth or projection 10 on the base of the machine,

a spring 11 normally holding a notch on the dial and the tooth in engagement,

The insole isifaositioned laterally by means of a pair of side gages 12 at the front endsof pivoted arms 13 mounted upon the studs 14: and connected by the inter-meshing gear segments 15. A spring 16 tends normally to force the side gages 1., toward one another,

such movement, however, being limited by means of an adjustable stop screw 17 mouhted upon one of said arms and adapted to engage an abutment 1'8'upon' the other; In:

order to prevent the insole from r ding up over the tops cf the' sidegages, the latter are provided with the horizontally proj'e'ct= ing portion 19 which project over the face the insole adjacent' the margin,

The power-actuating mechanism is substantially like that shown in the Cook application, and comprises a driving shaft mounted in suitable bearings in the rear of the machine, carrying an eccentric 21 and arranged to be driven from the constantly rotating belt pulley 22 through one-revolution clutch. mechanism 23.

The oscillating head or lever 25 is also similar to that shown in the Cook application, and comprises an open frame mounted to oscillate midway its ends upon hearing studs 20 in ears 2? rising from the base of the machine. Pivoted upon the oscillating lever near the rear end thereof are the knifecarrying arms or members 28, each having an upturned front end 29 provided with the rearwardly extending lip 30 through which passes the clamping screw 31 which engages the top of the head 25 and clamps the front end of the arm firmly against the head. The arms 28 are adapted to be adjusted to ward and from one another for insoles of different widths by means of the helical cams 32 mounted upon the shaft 33 carrying the adjusting handle 34:. A link 35 iscon nected at its upper end to the rear of oscillating head or lever 25 and is provided at its lower end with an eccentric strap surrounding the eccentric 22.

-'lhe work-engaging tools or instrumentalities carried by the oscillating head comprise two separate cutting knives 36, and a pressenfoot 37 for each knife connected therewith, these parts being carried by the arm or members 28, while an upper scoring tool 38 and two presser-feet 39 and all) are mounted directly upon the front end of the open frame, one of the presser-fect v 39 cooperating with the size marking dies mounted in the work table and the other presser-foot 4:0 cooperating with the width marking dies also located in the work table.

It will be observed that these various work-engaging tools are located at different distances from their axis of oscillation, so that if such parts were mounted rigidly upon the oscillating lever, variations in the thickness of the stock or work would inter- 1 fere with the proper action of these instrumentalities. Furthermore variations in the hardness or density of an insole beneath the different tools or instrumentalities might result in imperfect cutting or marking of the insole. To avoid these objections the different work-engaging tools have been mounted so that they may yield not only independently of one another, but also independently of the oscillating lever, so that no adjustment of the connection between the rear end of the oscillating lever and the eccentric is required when there is a change in the thickness of the stock being operated upon.

Secured to. the side of each end 29 of the lessee? knife carrying arms 28 by means of screws e01 on the plate or block 402, which forms wvith the upturned end 29 a vertical dovehaving the flange nearits upper end which enters an arc-shaped slot in the rear face of the knife. The knife carrier, and with.

it the knife and presser-foot, is normally held down by means of the spring d5 located between the extension 43 on the knife carrier and the projection 46 from the upper portion of the block 402 on the knife-carrying arm 28. A stop screw #27 mounted in the rcarwardly extending ear 48 at the top of the knife carrier limits the downward movement of the carrier under the action of spring l5. This spring is of suiiicient strength so that on the descent of the front end of the oscillating head 25 the knives will out into the insole until the presserfeet 37 contact with the surface of the sole, whereupon the springs will yield under further movement of the oscillating lever. The depth of incision is thus determined by the adjustment of the presscr-foot with respect to the knife, and in no way depends upon the thickness of the stock or the adjustment of the actuating mechanism.

The front end of the oscillating head ittion with the stop nuts 522 in engagement with the top of the lever 25 but which permit independent vertical movement after a predetermined pressure has been reached. As shown'in Fig. 8, the upper scoring tool 38 is provided with an offset worlnengaging edge and is detachably mounted upon the lower-end of its carrierlf) by means of a screw 53 so that it may be reversed as shown in Fig. 9 to vary the position of the scoring longitudinally of the insole with relation to the incisions.

T he work-engaging tools or instrumentalities mounted in the work table orsupport comprise aseries of size marking dies 55 mounted in a rotary carrier or wheel 56 fixed upon the shaft 6, a series of width marking dies 57 mounted in a slide bar 58 located in a transverse slot or groove extending across the work table, and a lower scoring tool 59 mounted upon or formed integral with a slide located in a second and narrower transverse groove extending across the face of the work table. The rotary carrier for the size marking die is so adjusted upon the shaft 6 that when the back gage is set for a particular size of insole the die bearing that number will. he in. position to engage the bottom face of the insole directly beneath the prersenfoot 39. The width mark ing slide bar 58 is adapted to be independently adjusted by hand to bring the die bearing the proper width letter in position directly beneath the presser-foot 40. A series of notches 61 on the rear edge of the bar is adapted to be engaged by'a tooth or projection 62 on the latch 63 having a finger piece (is and normally held in operative position by means of the coiled spring 65 as shown in Fig. 6.

In order to permit longitudinal variations in the position of the scoring on the under surface of the insole relative to the scoring or incisions on its upper face, there have been provided a second narrow groove 66 extending across the face of the work table. and also a blank slide '67, the surface of which is substantially flush with the surface of the ork tab e. This slide and the slide 60 which carries the lower scoring tool are intercha geable, so that the scoring on the lower side of the insole may be varied as desired.

The operation of the machine illustrated in the drawings is as follows:

The cutting knives and their presser-feet are first relatively adjusted to give the desired de 3th of cut and the knife-carr 'n 7 3.

arms are brought to the proper distance apart for the width of insole to be operated upon. The dial is then set for the size of insole thus adjusting the back gage and bringing the proper size die into operative position, and the width die is-adjusted' transver'sely of the work table to bring the proper width die into position. The insole is now inserted heel first between the side gages and beneath the projections carried thereby and pushed backwardly until the heel end contacts with the back gage. The trip-for the one-revolution clutch is then operated,

whereupon a single revolution is given the" driving shaft, causing the oscillating head to be actuated and bringing the instrumentalities carried by the front end of said lever into contact with the work; The knives cut into the face of the insole until their presser-feet engage the surface of the insole, whereupon the knife carriers head. T he presser-foot' 39 forces the insole against the size marking die, yielding when a predetermined pressure is exerted. Thepressenfoot 4O forces" the work against the width marking die and also yields when the predetermined pressureis reacheda The yield in the upper scoring blade scores the upper surface of the work at the same time that the lowerscoring tool marks the lower surface, the upper blade yielding when a predetermined pressure is exerted. The latter porto, but may be embodied in many difierent forms and constructions.
